ENGINE.

To all whom it may concern:

Be it known that 1, ANDREW W. FINDELL, citizen of the United States, residing at the township of Spring Vale, in the county of Isanti and State of Minnesota, have invented certain new and useful Improvements in Engines, of which the following is a specification.

This invention relates engine of the rotary type and the ion is to provide an engine having an improved valve construction and to further provide improved valve operating means. v

Another object of the invention is to provide an improved type of piston so constructed that as the piston moves, gate to an improved valves will be opened and closed.

' travel which are carried by .yieldably held Another object of the invention is to provide an engine so constructed that it will be comparatively simple in construction and at the same time strong and "durable and not liable to easily get out of order.

1 This invention is illustrated in the accompanying drawings, wherein Figure 1 isa view showing-the engine in side elevation. Fig. 2 is a vertical sectional view through the. engine, the pistons being shown in elevation. Fig. 3 is a transverse sectional View through the engine. Fig. 4 is a view of one of the gate valves forming part of this engine. Fig. 5 is a fragmentary view of the piston pistons in elevation.-

This engine is formed of two sections 10 and 11 which are formed as shown in Figs. 1, 2 and 3 and are connected by means 0 bolts 12 and when connected provide a circular chamber 13 in which the pistons 14 the disk 15. In order to prevent leakage, the disk 15 is positioned between packing rings-16 and the pistons 1 1 are provided with packingrings 17. Cam ribs 18 are formed upon these pistons 14 as shown in Figs. 2 and 5 in order to engage and open the gate valves 19 as the engine rotates, the gate valves being hingedly mounted as shown 1n F1g. 2 and in the closed posltion shown by means of springs 20. The gate valves 19 are positioned adjacent the compartments 21 which form combustion chambers and are positioned diametrically opposite each other. Covers 22 are provi Specification of Letters Patent.

combustion chambers 21, the covers being provided with fulcrums 23 for the levers 24. These valve actuating levers 2 1 are provided with slotted heads 25 which engage the stems 26 of valves 27 so that when the levers are moved in one direction the valves will be opened and fuel may pass through the pipes 28 into the combustion chambers 21. These levers 24 are pivotally connected with links or draw rods 29 extending inwardly and having their inner ends provided with rollers 30 positioned in the grooves 31 of the cam heads 32 carried by the disk 15. Therefore as this disk rotates thevalves 27 will be opened and closed in timed relation to the rotation of the disk obtained. When this engine is in use, the disk 15 rotates, the fuel being supplied to the combustion chambers through the opening and closing of the valves 27 at the proper time and this the medium of the spark plugs 33. The gate valves 19 which are opened through the medium of the cam and thus the proper action ribs 18 and closed by means of springs 20-are provided to prevent back-firing. As this engine is operated, the live gas between the gate valves and the rear ends of the pistons will be exploded and the burnt gases will be driven out through the exhaust pipes 34 the burnt gases of course being in front 0 I have therefore provided an is simple in construction but which is strong and durable and very efflcient in operation.

What is claimed is An engine comprising. a casing forming an endless cylinder chamber, and having an' open central portion the casing being provided with combustion chambers communicating with said cylinder chamber, a disk rotatably carried by said casing to extend across the open central portion'thereof' and surrounded by the cylinder chamber, pistons extending from said disk into said endless cylinder chamber, gate valves pivotally mounted in said combustion chambers, and yieldably held to extend across said endless cylinder chamber, fuel inlet pipes communicating with said combustion chambers, valves for said fuel inlet pipes, levers pivotally connected with the stems of said valves, a neck extending from the center of the said disk, a head carried by said neck and progroove in its outer face,

- cam sopene and closed as said disk rotates, and

links a pivotally connected vwith said levers and provided with rollers positioned in said roove whereby said valves will be outlet pipes leading from said endless cylinder chamber between said combustion chambers.
